To (11H who/1t it may concern.-

Be it known that I, GODFREY J. KAPLAN, a citizen of the United States, residing at Owatonna, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements in Combined Ohurns and Butter-Yorkers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to combined churns and butter-workers, and, generally stated, has for its objects to simplify the construction and improve the action thereof.

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

One of the salient features of this invention is directed to the construction and arrangement of parts whereby the drum and the rollers or rotary parts within the same may be driven at the same speed both in the churning and butter-working actions, thus making unnecessary the use of a two-speed drive in order to adapt the machine for use both to churn and work the butter.

The invention also involves other novel features of construction, as will hereinafter more fully appear.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in side elevation, showing the improved churn. Fig. 2 is a plan view of the same. Fig. 3 is a detail with parts broken away, taken through one of the so-called paddle-rollers in the drumheads on the line 13 m of Fig. 5. Fig. 4 is a detail in end elevation, showing one of the roller-shaft bearings. Fig. 5 is a vertical section taken transversely through the machine on the line a x of Fig. 1, and Fig. 6 is a transverse vertical section taken on the line 00 0c of Fig. l.

The numeral 1 indicater the rotary drum of the machine, which drum is horizontally disposed, has fixed heads, one of the heads being provided with a rigidly-secured gudgeon 2 and the other head having a rigidlysecured spider-bracket 3. The gudgeon 2 1s journaled in a suitable bearing of a bearingbracket 4, and the spider-bracket 3 is provided with a hollow gudgeon 5, that is journaled in a suitable bearing of a bearingbracket 6. As shown, the bearing-brackets 4 and 6 are rigidly connected at their lower side portions by long tie-rods 7. The bearing-bracket 6 is provided with a horizontallyextended skeleton bearing-shelf 8, having suitable bearings in which a counter-shaft 9 is journaled. This counter-shaft extends below but parallel with the axis of the drum, and at its inner end it is provided with a spur-pinion 10 and at .its outer end is shown as provided with a loose pulley 1]. and a fixed pulley 12. The pinion 10 meshes with a large internal ring-gear 13, that is secured to the adjacent head. of the drum 1. The drum 1. is shown as provided with the usual doors 14 for affording access thereto to the interior thereof when open.

Mounted within and carried by the drum is a pair of deeply-corrugated reverselydriven so-called paddle-rollers 15 and 15 These paddle-rollers are located on opposite sides of the axis of the drum and are so spaced that a passage for the butter which is worked between the rollers is provided at the axis of the drum. At their left-hand end (directions being taken with respect to Figs. 1, 2, and 3) the rollers 15 and 15" are provided with countersunk bearing-caps 16, that are journaled on gudgeons 17, that project inward through the left-hand head of the drum and are secured to or formed integral with bearing-plates 18, which in turn are detachably secured to the said drum by means of wood-screws 19 or other suitable devices. At their other or right-hand ends the said two rollers are provided with countersunk bearing-caps 20, which are like the bearing caps 16, except that they are provided at their outer portions with diamnietricallyextended pin-seats 21.

Secured, as shown, to the right-hand head of the drum and set partly into the same in axial alinement with the adjacent bearingcaps 20 of the two rollers are shaft-bearings 22, that are provided with diametricallyextcnded pin-seats 23. Short roller-driving shafts 24 are ournaled in the shaft-bearings 22 and in the spider-bracket 3. The projecting ends of these shafts 24 normally en- 'vided with a half-clutch 32.

gage with the respective bearing-caps of the said rollers, and the said shafts are provided with diametric driving-pins 25, that normally engage the pin-seats 21 of said bearing-caps, so that the said shafts and rollers are then connected for 00111111011 rotation. It will of course be understood that the bearing-caps 16 and 20 are secured for rotation with the respective rollers. Secured to the shafts 24, just outside of the shaft-head of the drum, are small spurgears 26.

Journaled in and extending through the hollow gudgeon 5 of the spider-bracket 3 is a short counter-shaft 27, which at its inner end is provided with a small gear 28, that meshes with the gears 26 of that one of the shafts 24 which is connected to the paddle-roller 15. The gear 28 also meshes with an intermediate gear 29, that is loosely j ournaled to the adjacent head of the drum and meshes with the gear 26 of the shaft 24, that is connected to the roller 15. A larger spur-gear 30 is secured to the outer end of the counter-shaft 27. 011 the lower or driving counter-shaft 9 is a relatively large spur-gear 31, that meshes with the said gear 30. The spur-gear 31 is loosely journaled on the shaft 9, but is held against axial movements thereon and is pro- The half-clutch 32 is adapted to be engaged by a half-clutch 33, that is mounted to slide on but to rotate with the shaft 9 and, as shown, is adapted to be moved at will by a shipper-lever 34, pivoted to the bearing-shelf 8 of the bearingbracket 6.

Within the drum, adjacent to the roller 15, is a lifting-shelf 35, that preferably extends from end to end of the drum and is so disposed that it will lift the butter on the rising side of the drum and lift the same onto the said roller 15 or between said roller 15 and the roller 15. At the opposite side of the drum, adjacent to the roller 15, is a similar lifting-shelf which not only serves to lift the butter and to deliver the same against the roller 15 but acts as an abutment and cooperates with the said roller 15 to work the butter downward between said shelf 35 and said roller 15 when the two are moving upward on the rising side of the drum.

The rollers, as well as the drum, should be driven both i in the churning and butterworking actions, and the said parts will be so driven when the fixed pulley 12 and shaft 9 are driven and the said half-clutch. 33 is engaged with the halfclutch 32 of the loose gear 31. Assuming the drum to be driven in the direction of the arrow marked thereon in Fig. 5, the two rollers will be driven as indi cated by the arrows marked adjacent thereto in said view. In the butter-working action, under that part of the rotation of the drum which carries the lifting-shelf 35 up ward on the rising side of the drum, the said shelf will deliver the butter onto the roller 15, which rotates in the same direction as the drum, and the butter thus raised will be worked downward between the two rollers 15 and 15. tation of the drum, which carries the shelf 35 upward on the rising side of the drum, the said shelf carries the butter against the roller 15*, which is rotated in a direction reverse to the direction of the rotation of the drum, and the said roller 15 will then cut and crowd the butter downward through the passage between the said roller 15 and shelf 35. This latter-noted action will be more clearly understood by observing Fig. 5 when the said view is turned upside down. In the butter-working action the long projecting ribs of blades of the so-called paddle-rollers 15 and 15 in addition to the actions above noted have a paddling or patting action on the butter, which is very much like that of a handoperated butter-working paddle. In the churning action the blades of the said rollers strike in rapid succession the cream directed thereto by the lifting-shelves and produce concussions which are very conducive to rapid churning. Said lifting-shelves themselves continuously raise and drop the cream within the drum, producing other concussions which also hasten the churning ac tion of the cream.

After the cream has been churned it is desirable to give the drum several rotations without rotating the rollers on their own axes, and this action is produced when the drum is rotated, while the half-clutch 33 is thrown out of engagement with the halfclutch 32 of the roller-driving gear 31.

When it is desired to remove the rollers 15 and 15 or either thereof, the dri vingshafts 24 are drawn outward, so that their drivingpins 25 are moved out of the seats 21 of the bearin -caps 20 and are drawn into the seats 23 of the shaft-bearings 22. These outward movements of the shaft 24 carry the inner ends thereof out of the said bearing-ca s 20.

Where the parts are constructed wit 1 suf 'licient play, the loosened ends of the rollers may then be swung sidewise and the rollers moved endwise, so as to carry the bearingcaps 16 off from the gudgeons 17 of the bearing-p-lates 18. Where there is not sufficient play to permit the removal of the rollers in the manner above described, the bearing plates 18 must be removed, so as to draw their gudgeons 17 out-ward and out of the bearing-caps 16. In either case the rollers may very easily be removed from working positions within the drum. Normally the shafts 24 are held against endwise .movements by collars 36, that are secured to said shafts by set-screws or similar devices.

I claim as my invention 1. In a combined churn and butter-worker,
